Since federal prosecutors released charging documents for the college-admissions scandal over a year ago, one of the most intriguing pieces of the puzzle has been the allegedly staged photos of students on workout equipment. The photos were submitted to the athletic departments at elite universities as “proof” of students’ merit, reportedly. But how could supplying a photo on a piece of equipment at the gym, which any kid with access to a YMCA could take, help convince administrators of a student’s athletic accomplishment? It was an oddly simple gesture, but also seemed like a whole lot of effort.

Now, per People, prosecutors have released photos of Lori Loughlin and Mossimo Giannulli’s daughters, Bella Rose and Olivia Jade, on rowing machines, which they claim the couple sent to the scheme’s ringleader, William “Rick” Singer, at his request. The feds argue that Loughlin and Giannulli defrauded the school by paying half a million dollars to Singer. In exchange Singer allegedly shepherded their daughters into the University of Southern California by presenting them as coxswain recruits for the crew team, though they did not participate in the sport. The couple denies this, and argues that they believed they were simply making donations to the school.

The court documents released also include emails allegedly between Giannulli and Singer from 2016, in which Singer requested the photo of their eldest daughter on an ergometer, aka “ERG,” aka rowing machine. Giannulli obliged. “Lori and Moss, I met with USC today [and] I need a PDF of her transcript and test scores very soon while I create a coxswain portfolio for her,” Singer wrote. “It would probably help to get a picture with her on an ERG in workout clothes like a real athlete too.”

Giannulli said, “Fantastic. Will get all.” According to the documents, he sent the photo on September 7. The same request was made the following year for their youngest daughter. Giannulli obliged again, on July 28, 2017, and Loughlin was CC’d.

According to People, the feds released these documents in response to the motion filed on behalf of Giannulli and Loughlin to dismiss the criminal case. Their attorney’s have claimed that the feds withheld evidence and bullied Singer into lying about how much Loughlin and Giannulli knew in terms of where their money was going and how it was applied.

Their trial is still set to start in October of this year, and will be carried out alongside several other parents who were charged on similar grounds.
